Does that mean "you need conscious decisions for multiverse histories to be conscious of..." 

If so, then yes: consciousness can't exist at all in the absence of consciousness.

What does 'seeing macroscopic divergence' mean? Presumably it doesn't mean 'being conscious of more than one universe'. Perhaps it means the existence of apparent randomness affecting macroscopic observables. But you don't need consciousness for that. All you need is amplification, which happens all the time and doesn't need any specially designed equipment.

It sort of puts MWI in the dock for *your* having put conscious observers at the heart of things, contrary to the predictions of quantum theory. Those are that multiple, approximately decoherent histories are a generic phenomenon in the multiverse.
